CARBONARA, OF ROGK'V'ILLE CENTER, NEW YORK, ASSIGNOR TO PIONEER YORK, A CORPORA- INSTRUMEN'I COMPANY, INCORPORATED, BROOKLYN, NEW TION OF NEW YORK NAVIGATION LIGHT Application filed January 11, 1930.: Serial No. 420,057.

This invention relates to navigation 14, ofthe material of base-plate, 12. Hinge, lamps. r '13, and bracket, 14, are means by which a Among the objects otthe invention is to lens-retaining loop, 15, may be maintained provide a v navigation lamp having but a few in engaging relation with the lens for the parts and which may be manufactured inexpurposes of securing the lens to the base-.

Preferably, the lens-retaining loop may be the invention is to provide a lamp mounting, formed of a metallic wire which takes the having novel means for securing ashell or general shape of the lens, 10, and it can be lens in place and which enables theready easily sprung laterally of the lens for the replacement of a'lamp or the cleaning of its purpose of engaging and disengaging the shell or lens. Other objects of the invention open ends, 16, 17, with bracket, 14, when the will appear from a detailed description of lens is held in a mounted position. For enthe same which consists of the features of suring firmness of fit between the lensand base-plate it is convenient to form the split- 15, with its ends, 16, 17, spaced apart as IV and'with its side-pormost extreme conditions. Another object "of after described and claimed.

In the drawingI have illustrated a preillustrated in Fig. ferred embodiment of my invention and tions curved away from the base-plate, as Fig. I is a plan thereof embodied in an aeroillustrated in Fig. V. A resilient split-loop nautical navigation lamp. having an initial normal form of such con- Fig. II is an elevation of the lamp shown figuration will firmly girdle the lens and also in Fig. I with part of its shell or lens broken urge the same against the base-plate.

Bracket, 14, has two slots, 18, 19, which away.

While this arand lens-retaining loop illustrated in Fig. IV. rangement of slots, 18, 19, is asymmetrical Aeronautical navigation lamps are deone its main attribute resides in the locksigned so as to be capable of mounting on ing security obtained by the cooperation of vertical and horizontal surfaces and possess the crimp, 20, and engaged relation of ends, a stream line form.

While I have disclosed my invention in connec ion with an aeronautical navigation lam of a particular design, it is apparent that the invention may serve to associate a lens or'shell having another form to a base-plate of suitbase-plate, 12,-

i9 able form and that other alterations and i pivotally mounting said modifications coming within the scope of the appended claims are contemplated.

. What is claimed'is': 7

A 1. The combination with a-base-plate, a lamp mounting carried thereby and I a lens enclosing the lamp mounting, of means for detachably securing the lens to the base-plate, 1

substantially equal to the'area of said base- 1 plate and a groove adjacent and borderin its open area, an open end-loop pivotally I supported'on said base-plate, and means holdv stantially flat reducing the ing the ends of the loop in locked position: tomaintain the-loop in the groove of said lens whereby the lens is secured to the baseplate. 1

3. A lamp mounting for a navigation light comprising in combination a base plate, means extending from said base plate for support- .ing a lamp, a lens enclosing said lamp supporting means, said lens having a substantially planar open side adapted to be closed by said base plate, and means for detachably securing the lens to thebase plate, said means comprising a resilient lens-engaging member havr g separable ends which are adapted to be locked together and having a portion there of pivotally secured to said base plate, and

means for detachably connecting the ends of I said resilient member .to' the base plate when the lens is held thereby. I 4. Alamp tion light comprising in combination a subbase plate having an oval shaped contour, means extending from said g 'the base plate wsignature.
